LPCXpresso54618 CAN-FD Kit

[okangokalp]

Hello, I want to communicate with two different modules in the lpcxpresso54618 nxp development module, the cards I want to communicate at 500kbps cannot send messages to each other. I do not encounter any problems when the codes and cards that I have debugged are working alone, but when they work together, I cannot see an output or get an error.
I am very grateful to those who support this!

Hello @okangokalp,

To narrow down your issue, let's check the following:

• Connection with your CAN cable.
• Definition of which CANx are you using in your program.
• Jumpers settings on your board or Shield.

Could you please give me more information of how you are doing your communication? How do you are sending messages in your CAN-FD configuration? Are you using CAN0 to CAN1 or CAN0 to CAN0?

Regards, Raul.

First of all, I have a bigger problem, when I run my code I get the error debug launching project.axf and I can't actually communicate with my card to my computer or any other card.
